SYNOPSIS

dmidecode [-s string] [-t type] [--dump-bin file] [--from-dump file]

dmidecode reads the DMI (Desktop Management Interface) table, also known as SMBIOS (System Management BIOS), and displays hardware information in a human-readable format. This includes details about the BIOS, system, baseboard, chassis, processor, memory, and other components.

PARAMETERS

-s, --string keyword

Only display the value of a specific DMI string (bios-version, system-serial-number, processor-version, etc.)

-t, --type type

Only display entries of specified type (bios, system, baseboard, chassis, processor, memory, cache, connector, slot)

-q, --quiet

Less verbose output

-u, --dump

Show raw DMI data

--dump-bin file

Dump DMI data to a binary file

--from-dump file

Read DMI data from a binary file

-h, --help

Display help

-V, --version

Display version

CAVEATS

Requires root privileges. Information accuracy depends on the BIOS/firmware implementation by the manufacturer.

HISTORY

Developed to provide a standardized way to access system hardware information on x86 and x86_64 systems through the SMBIOS standard.
